Hemut Prein was hired to be gaffer to Passion cinematographer Jose Luis Arcaine (pictured above, with Brian De Palma). Prein has shared pictures and technical information about the fluorescent lights used for Passion with the Cinetel website. Prein states that it was his idea to have a package of fluorescent lights shipped in to the set from Madrid, where they were built by Cinetel according to the specifications of Alcaine, who pioneered the use of such lights as the key source in film lighting. Prein provides technical details about use of the lights, and also some photos, two more of which appear below. (Thanks to Chris for telling us about the photos!)
